Brewed a NB Sierra Madre 1 Gallon extract kit the other day. I was a bit worried about the yeast. When I pitched it, the stuff just kinda sank and that was it for a day or two.
This morning I woke up to a nice thick,white fluff of krausen on the top!
I rigged up a blow off tube and have not noticed any bubbles at all. Most likely this is because the screw top to the 1 gallon bottle doesn't fit well. I secured it with some electrical tape, but my guess is that it's pretty leaky.
